opening attachments first displays pop-up to confirm
With certain file type attachments (DOC*, XLS*, jpg), when dubble clicking, a popup window appears, asking to select an action: save or open and with what program (see attached jpg). Other attachments open immmediately (e.g. PDF) without the popup window.
Under preferences - general I can influence this default action, but with the mentioned file types still the popup appears every time.
Any suggestions / solutions?
